Because the Original KD's have been the go to riding sunglass for over thirty years, they are an inextricable part of the biker culture. Not just in an obscure way, but in a very personal way. We have been sent photos of entire wedding parties wearing KD's; images of three generations of grandfather, father and son wearing KD's; and many couples smiling in their KD's on their way to the next motorcycle rally. Somehow the Original KD's join together the past, present and future...a constant in a rapidly changing world. But the main reason for their enduring popularity is that they are one tough, affordable biker sunglass.
